Interior of a monumental circular throne room inside a massive stone tower. The architecture is a blend of Romanesque and dwarven fortress styles, with colossal fluted stone pillars and high vaulted ceilings. In the center, a majestic throne made of dark stone atop a multi-tiered circular dais. Warm sunlight streams through high, narrow slit windows, illuminating dancing dust motes and intricate geometric carvings on the floor. Behind the throne, a massive arched window overlooks a canyon with waterfalls. Atmosphere is solemn and ancient. Cinematic lighting, photorealistic, 8k, epic scale.
